HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 706, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 477, 706, 681 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 477, 706, 681 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 477, 706, 681 is 1.
HCF(477, 706, 681) = 1
HCF of 477, 706, 681 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 477, 706, 681 is 1.
Highest Common Factor of 477,706,681 is 1
Step 1: Since 706 > 477, we apply the division lemma to 706 and 477, to get
706 = 477 x 1 + 229
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 229 and 477, to get
477 = 229 x 2 + 19
Step 3: We consider the new divisor 229 and the new remainder 19, and apply the division lemma to get
229 = 19 x 12 + 1
We consider the new divisor 19 and the new remainder 1, and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 477 and 706 is 1
Notice that 1 = HCF(19,1) = HCF(229,19) = HCF(477,229) = HCF(706,477) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get
681 = 1 x 681 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1
Notice that 1 = HCF(681,1) .
